Probable cause

The loss of propeller control for reasons that could not be determined because postaccident examinations revealed no anomalies that would have precluded normal operation and the airplane’s subsequent collision with power lines during the forced landing.

NTSB narrative

The airplane experienced a loss of propeller control during cruise flight, which resulted in the pilot's inability to attain the propeller speed needed to maintain flight. The airplane struck a power line during the subsequent forced landing to a highway. Upon landing, the right main landing gear separated from the airplane, and the airplane veered off the road. Postaccident examination of the engine did not reveal oil supply obstructions to the propeller control system. Component level testing and examination of the propeller system, which was limited due to propeller damage, did not reveal any anomalies that would result in a loss of propeller control. The reason for the loss of propeller control could not be determined.

Analysis

Primary failure mode
Mechanical failure
First missed decision gate
